Abstract(s)
Personality pathology is often organized in two orthogonal axes representing variations in type and severity (Westen et al., 2006). The psychoanalytic model developed by Otto F. Kernberg and colleagues (e.g., Kernberg & Caligor, 2005) is an example of the second trend, consisting of a dimensional approach describing personality organization (PO) in a continuum ranging from normal-neurotic (NPO), through high and low borderline (BPO), to psychotic (PPO) levels. • In this model, borderline-level PO underlies most of the personality disorders considered in the categorical-typological approach held in DSM-IV-TR (APA, 2000). Kernberg’s approach is clinically useful in identifying subthreshold/higher level personality pathology poorly covered by DSM-IV-TR Axis II, and understanding different meanings in common symptoms according to underlying levels of PO (Caligor et al., 2007). • As an effort at operationalization, Kernberg and Clarkin (1995) created the Inventory of Personality Organization (IPO), a self-report questionnaire including 3 primary scales (57 items): Identity Diffusion, Primitive Defenses, and Reality Testing. IPO has been used to investigate the relationship of PO to psychopathology and measure structural change as a psychotherapy outcome (cf. Ellison & Levy, 2011). • IPO has been translated into several languages and latent structure has been tested with clinical and nonclinical population (Berghuis et al., 2008; Iragashi et al., 2009; Lenzenweger et al., 2001; Normandin et al., 2002; Smits et al., 2009), yielding 2- or 3-factor solutions for the 3 primary scales. However, a recent study of the original English-language version conducted with a large nonclinical sample suggests that a 4-factor solution provides a better fit, with factors representing Instability of Self and Others, Instability of Goals, Psychosis, and Instability of Behavior (Ellison & Levy, 2011).
